Stroke: Basic and clinical

Abstract

Tissue plasminogen activator (tPA) was first approved in the USA 25 years ago for those who had experienced a recent occlusion (<3 h) of a cerebral vessel. Now, advances in clot retrieval (stentriever), in concert with tPA, heralds new optimism for ischemic stroke victims, but adds more pressure to identify therapies that will minimize hypoxic damage, protect compromised cells, and promote rehabilitation. In the past preclinical investigations have been poor at predicting potential clinical therapy, but they have contributed enormously to understanding post-stroke pathology. Current clinical trials (www.strokecenter.org/trials) anticipate a broad range of approaches: from hypothermia, to cell therapy, to neuroprotection.
